Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] The foreign object falling warning device provided by this utility model is installed in the rail transit section. It can move vertically and rotate, and can be flexibly adjusted. It can cover the entire rail transit section without any blind spots. It can detect foreign objects falling in certain areas in a timely manner, thereby increasing safety.

[0027] See Figures 1-4 The diagram shown is a structural schematic of the foreign object falling linkage early warning device in rail transit sections provided by this utility model.

[0028] As shown in the figure, the rail transit section foreign object falling linkage early warning device provided by this utility model includes six components: base 100, support column 200, lifting mechanism 300, mounting box 400, rotating mechanism 500, and camera 600.

[0029] The support column 200 is fixed to the top of the base 100. The lifting mechanism 300 is installed inside the support column 200 and extends outward to connect with the mounting box 400. The lifting mechanism 300 can drive the mounting box 400 to move vertically. The rotating mechanism 500 is installed inside the mounting box 400 and extends outward to connect with the camera 600. The rotating mechanism 500 can drive the camera 600 to rotate.

[0030] Specifically, the base 100 is fixed to the ground to ensure that the device is placed firmly on the ground and to provide stable support.

[0031] The base 100 is specifically rectangular plate-shaped, with connecting holes 110 at its four corners, and insert rods 120 are installed in the connecting holes 110.

[0032] The insertion rod 120 is used in conjunction with the connection hole 110 to fix the device on the ground or in a specific installation position, ensuring the stability and safety of the device during use.

[0033] Furthermore, the support column 200 is a cylindrical structure with one open end and one closed end, and an internal mounting groove 210 is formed for the lifting mechanism 300 to be placed. The closed end of the support column 200 is connected to the top of the support column base 100.

[0034] like Figure 2 , Figure 3 The lifting mechanism 300 includes a lifting motor 301, a rotating shaft 302, a coupling 303, a lead screw 304, and a telescopic rod 305. The lifting motor 301 is fixedly installed at the bottom of the mounting groove 210 inside the support column 200. One end of the rotating shaft 302 is connected to the lifting shaft of the lifting motor 301. One end of the coupling 303 is fixedly connected to the other end of the rotating shaft 302. The lead screw 304 is connected to the other end of the coupling 303. The coupling 303 is used to connect the rotating shaft 302 and the lead screw 304.

[0035] The lead screw 304 has an external thread on its surface, and the telescopic rod 305 is a sleeve structure with an internal thread corresponding to the lead screw 304 inside. The telescopic rod 305 is threaded to the outside of the lead screw 304 through the internal thread and extends outward from the mounting groove 210 in the support column 200.

[0036] In practical applications, the lifting mechanism 300 with this structure drives the rotating shaft 302 to rotate through the lifting motor 301, and drives the lead screw 304 to rotate through the coupling 303. The lead screw 304 rotates and engages with the telescopic rod 305 through a threaded connection, enabling the telescopic rod 305 to move vertically.

[0037] Furthermore, the mounting box 400 is connected to the telescopic rod 305. The mounting box 400 is specifically rectangular and has an internal cavity in which the rotating mechanism 500 can be placed.

[0038] like Figure 4 The rotating mechanism 500 includes a rotary motor 502, a transmission gear 503, a bearing housing 504, a rotating shaft 505, a driven gear 506, and a turntable 507;

[0039] A rotary motor 502 is fixedly installed in the cavity of the mounting box 501. A transmission gear 503 is connected to the rotating shaft of the rotary motor 502. A bearing seat 504 is fixedly installed in the middle part of the bottom of the cavity of the mounting box 501. A rotating shaft 505 is located inside the bearing seat 504 and extends outward along the top of the mounting box 501. The rotating shaft 505 can rotate along the axis of the bearing seat 504. A driven gear 503 is provided on the outer circumferential surface of the rotating shaft 505. The driven gear 506 meshes with the transmission gear 503. A turntable 507 is fixedly installed on the top of the rotating shaft 505. A connecting part 508 is provided on the turntable 507, and it is connected to the camera 600 through the connecting part 508.

[0040] In practical applications, the rotating mechanism 500 with such a structure is driven by the rotary motor 502 to rotate the transmission gear 503. The transmission gear 503 drives the driven gear 506 that meshes with it to rotate, thereby causing the rotating shaft 505 fixed to the driven gear 506 to rotate. The rotation of the rotating shaft 505 drives the turntable 507 fixed to it, thereby causing the camera 600 fixed on the turntable 507 to rotate.

[0041] Furthermore, the lifting mechanism 300 drives the mounting box 400 to rise and fall, thereby enabling the camera 600 to rise, fall, and rotate.

[0042] Furthermore, the aforementioned connecting part 508 consists of two connecting ear plates 508a, which are arranged opposite to each other and have a space between them for the camera 600. The connecting ear plates 508a and the camera 600 are respectively provided with mounting holes. Fasteners are passed through the connecting ear plates 508a in sequence, and the camera 600 is connected to them.

[0043] To further improve the reliability of the lifting mechanism 300, a partition 306 is provided in the mounting groove 210 inside the support column 200. The partition 306 has a through hole in the middle and is connected to the groove wall of the mounting groove 210. It is sleeved on the rotating shaft 302 through the through hole, which can separate the lifting motor 301 from the coupling 303, the lead screw 304 and the telescopic rod 305, ensuring the smooth operation of the lifting mechanism 300.

[0044] The following example illustrates the working process of this utility model in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation on this solution.

[0045] The device is placed on the ground via the base 100. The bottom insertion rod 120 can be inserted into the ground or fixed in other installation positions. Simultaneously, the device can be further fixed in a specific position via the fixing holes 110 on the surface of the base 100. When the height of the camera 600 needs to be adjusted to monitor areas at different heights, the lifting motor 301 starts, driving the rotating shaft 302 to rotate. The rotating shaft 302 drives the lead screw 304 to rotate via the coupling 303. The telescopic rod 305 moves up and down due to its threaded connection with the lead screw 304. The movable installation of the telescopic rod 305 ensures its smooth lifting and lowering within the cavity of the support column 200. The partition 4 separates the cavity of the support column 200, ensuring the smooth operation of the lifting mechanism 300. When the camera 600 needs to rotate 360° horizontally, the rotary motor 50... 2. Upon startup, the rotary motor 502 drives the transmission gear 503 to rotate. The transmission gear 503 meshes with the driven gear 506, thereby driving the driven gear 506 to rotate. The rotation of the driven gear 506 causes the rotating shaft 505 to rotate under the support of the bearing seat 504. The rotation of the rotating shaft 505 drives the turntable 507 and the camera 600 on it to rotate horizontally, realizing all-round monitoring. The camera 600 is responsible for capturing images within the rail transit section, monitoring the situation of foreign objects falling in real time, and transmitting the captured video data to the control center or monitoring equipment in real time, providing important visual information for early warning of foreign object falling. Combining the images and video data captured by the camera 600, the control center or monitoring equipment can monitor and analyze the situation of foreign objects falling within the rail transit section in real time.
